I have built Sage from source (sage-10.4.tar.gz and sage-10.5.tar.gz) on
four machines with different architectures and different derivatives of
Debian. On all machines the jmol viewer for 3d plots works under 10.4
but not under 10.5. The RuntimeError Traceback is identical on all
machines. A copy of a Sage session is below. Except for the machine
specific info the Traceback is identical for each installation. As you
can see from the transcript, java is installed. It is used by jmol in
10.4. I don't know enough Python to see what the problem is. Any help
would be appreciated.
